.To all whom t may concern.-

Be it known that I, EDWIN E. ANGELL, ofi Somerville, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in `Methods of Printing, of which the following is a specification.

Thisinvention relates to the art of printing, and has particular reference to a method of indelibly or ineiiaceabl indicating the monetary value of checks, bonds, stock certificates, and similar commercial papers to prevent alteration thereof.

The object of the invention is to cause a coloring-matter to be so impressed in the paper as to show through it, preferably without rforating or puncturing the paper, wheree 'lilylany attemA t at alteration or the figures or racters wil expose an increased amount of color, and thereby disclose such attempt. In attaining this object my improved method prevents the alteration or raising of a check or similar commercial paper by embossing characters on the check and appl ing a strong color to the back or recesse part, which color may be caused to show through the front of the paper.

A further object oi' the inventionis to apply one colorsolidly on one side oi the pa er and another color in outline on the other sidev of the pa er, whereby an attempt at alteration wo d result in more or less blending of the two colors.- t

To these ends the invention consists in the process or method substantially as hereinafter described and claimed. In the accompanying drawings I have illustrated one embodiment -of a device or apparatus for carrying out my invention as hereinafter stated. Y

Of said drawings, Figure 1 represents a central longitudinal vertical section through the device or apparatus. Fig. 2 represents a section on line 2 2 ,of Fig. 1. Fig. 3 represents a section on line 3 3 oi Fig. 1. Figs. 4 and 5 are respectively a plan and sectional view of a portion ci a commercial paper having characters embossed thereon, said views representing the paper and characters as very much enlarged 1n order. to clearly indicate the location and application of the color- Similar reference characters indicate similar plarts throughout the several views.

T e base or frame of the device is represented at 10, said base having a table or sur- Vface 11 for the check or pa er 12 that is to be embossed and printed. A) suitable cover is indicated at 13. The frame is rovided with a horizontal bracket 14 a s ight distance above the' level of the table-surface 11.

Within the base are bearings 15 for a tubular shaft or sleeve 16, to which is rigidly secured a type-wheel 17, having raised characters that are adapted to emboss the pa er. Secured to the rear end of the tubular s aft or sleeve is a gear 18.

' A tubular arm or lever 19 is provided with ears 20, which are pivoted at 21 to the base. Said lever is formed with lateral arms 22, Fig. 2, and the bracket or frame portion 14 is provided with sockets or hollow bosses 23, containing springs 24 and plugs or plungers 25, said springs pressing the plugs or plungers upward against the under side of the arms 22, so as tonormally hold the lever in the position indicated in Fig. 1. The arms 22 are also rovided with uprights 26'at their outer en s, arms 27 being pivotedat 28 to said uprights and provided with inking pads or rollers 29. Springs 30 are connected with the arms 27 and to a pin 31, projecting from the top of the lever, said springs serving to normally hold the hiking-pads in contact with the characters of the upper type-Wheel, which will be presently described.

A shaft 32 is rotatively mounted in the tubular lever 19, and a gear 33 is rigidly connected with its inner end, said gear meshing with the gear 18 at apoint between and in alinement with the pivots 21 of the lever 19, so that movements of said lever will have no eifect upon the meshing of the gears.

`The upperI type-Wheel 34 is rigidl secured to the shaft 32 and is provided wit intaglio characters, corresponding in outline with the characters upon the type-wheel 17, but so formed as to press the paper downward around the edges of, the embossing-type upon said wheel 17. A handle 35 is secured to the front end of the shaft 32, and said shaft also has secured to it a disk or dial 36, provided with suitable characters corresponding with those upon the type-wheels and with marks to register with a pointer or indicator 37 upon IOC the cover 13. Inasmuch as such a dial-and pointer construction is well known it is not necessary to represent thecharactersborne by the disk 36.

Rising from the bracket or frame 14 is an upright 38, having a stop-pin 39 to limit the upward movement of thelever. A horizontal portion 40 at the upper end of the upright 38 is formed With a socket in which is mounteda plug or yielding stop or detent 41, having a convex or conical outer end. In the recess in rear of the plug or stop 41 is a spring 42. Said plug is formed with a recess or groove 44 to coact with a limiting pin or screw 45 to restrict the outward movement of the plug 41 under the influence of the spring 42. The said plug or detent 41 cooperates with either one of a series of holes 43 formed in the gear 33, said holes being preferably slightly smaller than the diameter of the detent 41, so that only the tapered or conical end portion of the plug can engage the mouth of a hole 43,l thereby enabling the shaft 32 to be turned, by means of the handle 35, by the employment of suflicient force to cause the detent 41 to slip out of engagement with said hole.

To sipply ink to the lower type-wheel 17, I provi e pads or rollers 46, carried by arms 47, pivoted at 48 to the base or frame of the machine and having springs 49 to press the inking-rollers against the type-wheel.

To limit the movement of the upper typewheel toward the lower type-wheel, I provide an adjustable stop 50 in the frame, said stop being adapted to coact with either one of a series of adujstable stops 51, mounted in a circular flange at the rear of the upper type- Wheel 34.

A wheel presser-foot to bear upon the surface of the paper that is to be embossed and printed is representedl at 52, said wheel being.

mounted upon a pin or stud 53, carried by a movable member hereinafter described.

The feed-wheel 54 is mounted on a pin 55, secured to the base or frame, a pinion 56 being fast with the feed-wheel 54. Said pinion 54 meshes with `a pinion 57, fast on a shaft 58, mounted in the tubular shaft orf sleeve 16. Secured to the rear end of the shaft 58 is a ratchet 59, adapted to be actuated byy a pawl 60, pivoted to the lower end of an arm 61 and connected to the latter by a spring 62, said arm 61 beingcarried by a rock-shaft 63, Fig. 3. The roc -shaft 63 is provided with an upper arm 64, Fig. 2, the end of which engages a perforated e'ar 65, projecting downward from the tubular arm or lever 19, so

that each downward pressure of the lever will cause the pawl60 to retreat from the .tooth of a ratchet, and upon the' succeeding upward movement of the lever under the inuence of the s rings 24 the pawl 60 will engage a tooth o the ratchet 59 and cause the shaft 58 to actuate the feed-wheel 54 to 'ad- Vance the check or sheet of paper a proper distance or step ready for the next impression due to another downward 1 iovernent of the lever and upper type-wheel.

A detent-pawl engages the ratchet 59 tov the edge of The type or -characters carried by the two type-wheels are such that those upon one wheel serve to emhoss and print solidly-colored characters, the color that will be deposited in the concavities, preferably the under side of the paper, depending upon the color applied to the inking-rollers 46. As has been stated, the type carried by the upper wheel are intaglio. merals upon the upper surface of the paper with an ink preferably of a contrasting color, due to whatever ink is applied to the rollers 29, the said characters of the upper typewheel depress the surface ofthe paper around the outer edges of the raised portions embossed by the characters of the lower typewheel. s

In Figs.v 4 and 5, which are enlarged or magnified considerably beyond the size actually employed forr check-printing, I have represented the ink or coloring-matter which is deposited bythe type-wheel 34 at a. The

ink or coloring-matter deposited by the lower 4 type-wheel17 is indicated atb. It will therefore be seen that the paper is'provided on one side with solidly-colored characters and on the other side with characters outlined in color, the colors depending upon the selection for the inking-rollers- It will also be understood that the coperation of the intaglio characters upon the one wheel with the embossing characters of theA other wheel serves to stretch the portions of the pape i sheet on which the coloring-matter b is applied, so that the said coloring-matter will be readily perceptible on the face of the sheet inside of the lines bounded by the ink or coloring-matter a. Any attempt to alter the characters will only serve to increase the amount of tint showing through the paper from the ink b and also tends to blend the colors a and b.

Of course it will be understood that when using the apparatus described for carrying out my improved method the rotation of the handle 35 brings any particular pair of characters of the upper and lower type-wheels opposite each other, due to the intermeshingA While they outline the letters or nu- IOO IIO

Y in so far that when, for instance, a 4 is uppermost on the lower wheel then the correspondin intaglio 4 of the upper type- Wheel will be opposite the 4 of the lower wheel.

Having now described my invention, I claim- 1. The method of indelibly marking or printing on sheets consisting 1n offsetting a portion of the surface of the sheet, depositing solid masses -of color in the concave side of the offset, and depositing an outline of color around the ed es of the offset portions.

2. The met od of indelibly marking on paper, which consists in compressing a sheet of paper between cooperating types or dies in the form of a conventional character, one ofrwhich is raised and solid having a lane printing-s'urface,` and the other of whic has projecting ribs separated by recesses adapted' to surround the solid type and forming the outlines only of the characters.

3. The method of indelibly markinor on paper, consisting in raising a portion of? the surfaceof the pa er having the form of a legible character o extended area and sharply definingthe edges of the character, inking solidly the concave side of the raised surface, and inkin edges of tle character and the surface of the sheet. I

4. The method of indelibly marking on paper, which consists in clamping a sheet of in the angles between the raised paper between co erating types, one of which is solid and t e other having an edge adapted to surround the solid t e, and applying ink to'opposite sides of t e sheet at the same time by means of said types.

5. Commercia paper having an offset or embossed portion colored in the concavity thereof, and the paper havin on its opposite side .a line following the e ges of t e embossed portion.

6. Commercial paper having a raised ortion formed as a le ible character colore on its concave side an surrounded on the opposite side of the paper close to its raised edges by a colored line.

7. Commercial pa er having a raised portion formed as a legi le character with an extended surface and sharply-defined edges,

and inked in the angles between the surface of the sheet and the edges of the raised portion.

8. Commercial pa er having a raised portion formed as a legi le character with an extended surface and sharply-defined edges, inked over the entire concave surface of the raised portion, and inked in the angles formed between the outwardly-extendin edges of the raised characterand the s ace of the sheet.

In testimony whereof I have affixed my signature in presence of two witnesses.
